The aim of this work was to study the effect of the solvent N-methylmorpholine-N-oxide (NMMO) to pre-treat Nannochloropsis oculata before the anaerobic digestion process. The results indicated that the pre-treatment affects the characteristics of the cell wall, which consequently becomes more susceptible to the microorganisms attack during anaerobic digestion. The methane production was increased by 43% after the pre-treatment, from 238+/-6mL<SUB>CH4</SUB>/g<SUB>VS</SUB> until 339+/-4mL<SUB>CH4</SUB>/g<SUB>VS</SUB>. On the contrary, the methane production from Chlorella vulgaris decreased after the pre-treatment from 251+/-4mL<SUB>CH4</SUB>/g<SUB>VS</SUB> to 231+/-3mL<SUB>CH4</SUB>/g<SUB>VS</SUB>. The failure on the pre-treatment was attributed to the particular characteristics of the substrate in consequence of a previous drying step.
